Awl
- Mac performing an operation using car parts. He even admits that he doesn't know if it'll work since he got a C in biology.
Chisel
- The Embassy gets in a siege all because Mac and the team chose it as the safest place to be from heavily armed terrorists.
Scissors
- Cyber-Terrorist group The Collective kidnap Riley's Mother to get her to do their bidding. They give her back only after locking her in a mechanical strangulation device like something out of one of the Saw movies. The entire team works feverishly to save her before an ever-tightening metal cable decapitates her. Yeek.
Magnifying Glass
- The Zodiac Killer making a return.
Muscle Car + Paper Clips
- Hackers disabling a VIP's pacemaker. Which is true since analysts have highlighted it as a serious concern.
X-Ray + Penny
- There's something chilling about the ease with which Murdoc breaks into Mac's house, incapacitates and kidnaps him. He gets away with his prisoner so neatly Jack declares the trail cold, and if the escape hadn't been part of Murdoc's plan, Mac would have been in real trouble.
"Skull + Electromagnet"
- Jack not wanting to go to the Bermuda Triangle.
- When Harper Hayes gets yanked off her feet by Mac's electromagnet, it looks like something from a horror movie: she rises from the ground with her eyes rolling back in her head like she's possessed. No wonder Jack fell to his knees and crossed himself!
War Room + Ship
- Mac gets to know a teacher onboard a ship that is saving the lives of her students through the two working together, with a particularly close relationship forming over video call — up until she has to perform a Heroic Sacrifice to make sure the ship only takes her down with it by sealing a flood long enough to keep the rest afloat in time for the Coast Guard to reach them. We get to see her start suffering from hypothermia, before the room slowly and gradually floods. There is no Deus ex Machina, nor any real theatrics as the video feed finally cuts off right before she drowns. Just an innocent hero of a teacher silently dying right before Mac's eyes thousands of miles away, and him being unable to do anything.
Bullet + Pen
- Murdoc breaking into Cage's apartment and shooting her.
Benjamin Franklin + Grey Duffle
- It's funny/scary to see Mac nervous above the ground.
Improvise
- The Double Subverted scare where Murdoc seems to resurface but doesn't then DOES and wastes Jill.
Specimen 234 + PAPR + Outbreak
- Specimen 234 is a class 4 super virus. It is decribed as spreading fast, like the flu, and has a 99% fatality rate. If it's released, it could kill millions.
Thief + Painting + Auction + Viro-486 + Justice
- Viro-486 was tested to prove the bioweapon is worth using... on a live human.
